Charlotte - Classic, but overdone. Spice it up with a funky middle name or something.Kennedy - I know a few, but still not a huge fan. Leah - Pretty, but bland.Emeline (pr: emma line) - Not bad, but you're likely to have pronunciation issues. Florence - my favorite off your list! Elegant, unusual but not weird, and flowy.

Boys:Kael - I'm familiar enough with it to know it's not made up, but I still don't really like it. It just makes me think of the vegetable Kale.
Cree - Sounds like Creed, which is a little much unless you're very religious.Everette or Everett - Everette looks like a girls' name. Everett's not bad.David (family name) - Solid, but classic. I like it, but beware of the nickname Dave, which I don't.

Girls:Charlotte - It's a nice name, but I am so tired of hearing it lately!Kennedy - Sort of like, because when my mother would call my name quickly, it sounded like Kennedy, so that grew on me.Leah - Dislike.Emeline (pr: emma line) - I pronounce this name differently and I prefer how I say it to Emma-line. Not a huge fan.Florence - I like this name a bit, but it's unusable for me. I'd say go for it.

Boys:Kael - Kind of like it, but more for someone else rather than me.
Cree - Prefer for a girl.Everette or Everett - I like Everett spelling. The other one just seems girly. Everett is a handsome name.David (family name) - Don't mind it as a middle name but it's not "stunning" as a first name for me.
